Differentiate between primary and secondary cells, citing some examples for each.
Differentiate between primary and secondary cells, citing some examples for each.
Following are the differences between a primary and a secondary cell:
1. In a primary cell, the electrochemical reaction occurring in the cell is not reversible; while in a secondary cell, the electrochemical reaction occurring in the cell is reversible.
2. A primary cell is designed to be used once and discarded, and not recharged with electricity and reused; while a secondary cell is rechargeable and can be used again and again by passing current through it.
3. Primary cells have a lower initial cost; while secondary cells have a higher initial cost.
4. Examples of a primary cell are leclanche cells, Daniel cells, dry cells etc; while examples of secondary cells include a lead-acid accumulator, nickel cadmium, nickel metal hydride, lithium ion (Li-ion) etc.
